• MBOX files can get oversized due to large storage thus resulting in file corruption.
• Less data security as MBOX files cannot be encrypted or password-protected.
• Not sufficient for large mailboxes with big attachment files as storage is limited.
• No support for metadata, i.e., lacking in major email features.

All of this results in slowed performance and difficulty in integrating with advanced features and applications.
